(Au)
Jean felt his cellphone vibrate in his pocket. Probably it was the reply. Oh, he forgot to delete the number. Pushing the thought out of his mind, he leaned on his fist scrutinizing the disgusting book that happened to be on the table. This stuff was worse than algebra. Heck, stupid proving and math theorems. He didn't even want to freaking pay attention anymore. Jean made up his mind to ask Marco to teach him the lesson ... again.
Marco spotted the lines of stress appearing on Jean's forehead.
Wait, why was he watching Jean again? He felt heat rise to his face as he turned away quickly. He had to pay attention. Slamming his fist (lightly XDD) onto the table, he let out a little sigh and closed his eyes.
He was fine now, perfectly fine!
Until a paper airplane hit him on the head. For a second there, he wanted to frown. But he had to control it, weird things happened if he didn't smile. For example, he frowned earlier and part of the ceiling broke, hitting Jean on the head.
Turning around to face the source, he spotted Jean waving at him and giving the sign. Which meant he didn't get the lesson. Now he has to pay extra attention so he could teach Jean!
"Focus, Marco. Focus!" He repeated over and over on his head.
The symbols began to look less like ancient runes and more like numbers. That was a good sign. A few decades (hours) later, he finally knew the lesson.
